Well...yeah we kinda do. In the sense that we have telescopes that can observe the remnants of the big bang (cosmic microwave background radiation - CMB). So we do have telescopes that witness a big bang.

You do not believe in dragons and unicorns? Seamen always had a lot of imagination but the "Water Unicorn" exists. It is just a whale but what do you think goes through a persons mind after a year in a tub. Dragons, fairy tale. Of course I know that men and dragons never lived together if you refer to dinosaurs that in some species look astonishingly exact like a dragon. But that was found out a long time later. I wait to see what pops up next. Afterall until the earth was declared a ball there was a lot of evidence for the contrary. Mass extinction was the idea of a few fools they told me when I attended school. Now we all know what the meteorites did. Who knows, maybe god shows up afterall. Until then, no worshipping though.
